The Hyperlogos

Moteur Developpment International (MDI) is Guy Negre's air-electric hybrid vehicle company. While they have not yet (September 2007) produced any significant quantity of vehicles, they have allegedly for several years performed pilot projects in Spain using their Mini C.A.T. vehicle as a Taxicab.

Moteur Developpment International (MDI) is Guy Negre's French automaker which has designed the CAT series of air-hybrid vehicles, and their related power systems.

First mentioned in 2001, the eCycle Diesel-Electric Hybrid Motorcycle was one of the most eagerly awaited vehicles ever prototyped. True, its top speed is limited to around 80 MPH, and takes six seconds 0-60 (good for a car but not so hot for a motorcycle) but the vehicle was reputed to get 150 to 180 miles per gallon - three times that of a typical hybrid auto.
